saurus  from  Kimmeridge  Bay,  agreeing  in  the  characters  of  the 
teeth  with  the  form  for  which  he  formerly  proposed  the  establish- 
ment of  the  genus  Enihekiodon.  The  specimen  includes  the  skull, 
a  large  portion  of  the  vertebral  column,  numerous  ribs,  the  bones  of 
the  breast-girdle,  and  some  limb-bones.  The  first  forty-five  ver- 
tebral centra  have  a  double  costal  tubercle.  The  coracoids  have  an 
unusual  form,  being  more  elongated  in  the  axial  than  in  the  trans- 
verse direction,  and  this  elongation  is  chiefly  in  advance  of  the 
glenoid  cavity.  The  articular  end  of  the  scapula  is  very  broad. 
The  paddles  are  excessively  reduced  in  size,  the  anterior  being  larger 
than  the  posterior,  as  evidenced  by  the  comparative  size  of  the  prox- 
imal bones.  The  species,  which  the  author  proposed  to  name  /.  en- 
ihekiodon, most  nearly  resembles  the  Liassic  /.  longirostris  and  /.  te- 
nuirostris.  The  length  of  the  preserved  portion  of  the  skeleton  is 
about  10  feet ;  the  femur  measures  only  2  inches,  and  the  humerus 
2*7  inches. 
3.  "  Note  on  a  Fragment  of  a  Teleosaurian  Snout  from  Kim- 
meridge Bay,  Dorset."     By  J.  W.  Hulke,  Esq.,  F.R.S.,  F.G.S. 
In  this  paper  the  author  described  a  fragment  of  the  snout  of  a 
Teleosaurian  obtained  by  J.  C.  Hansel,  Esq.,  F.G.S. ,  from  Kimmeridge 
Bay,  and  which  is  believed  to  furnish  the  first  indication  of  the 
occurrence  of  Teleosaurians  at  Kimmeridge.  The  specimen  con- 
sists of  about  17  inches  of  a  long  and  slender  snout,  tapering  slightly 
towards  the  apex,  where  the  praein  axillae  expand  suddenly  and 
widely.  The  nostril  is  terminal  and  directed  obliquely  forwards ; 
the  prsemaxillae  ascend  2-5  in.  above  the  nostril,  and  terminate  in 
an  acute  point;  and  each  praemaxilla  contains  five  alveoli.  The 
lateral  margins  of  the  snout  are  slightly  crenated  by  the  alveoli  of  the 
teeth,  of  which  the  three  front  ones  are  smaller  than  the  rest :  most 
of  the  teeth  have  fallen  out ;  but  a  few  are  broken  off,  leaving  the 
base  in  the  sockets.

AN  EXPLOSION  ON  THE  SUN.       BY  C.  A.  YOUNG. 
ON  the  7th  of  September,  between  half-past  12  and  2  p.m.,  there 
occurred  an  outburst  of  solar  energy  remarkable  for  its  sudden- 
ness and  violence.  Just  at  noon  the  writer  had  been  examining  with 
the  telespectroscope*  an  enormous  protuberance  of  hydrogen  cloud 
on  the  eastern  limb  of  the  sun. 
It  had  remained  with  very  little  change  since  the  preceding  noon 
— a  long,  low,  quiet-looking  cloud,  not  very  dense  or  brilliant,  nor 
in  any  way  remarkable  except  for  its  size.  It  was  made  up  mostly 
of  filaments  nearly  horizontal,  and  floated  above  the  chromosphere  f 
*  This  is  the  name  given  by  Schellen  to  the  combination  of  astrono- 
mical telescope  and  spectroscope.
